| Summary: | Nanostructured material of layered organic-inorganic hybrid nanocomposites can be
generated by encapsulation of an organic moiety into an inorganic lamellar in which
the open lamellar systems such as layered double hydroxides (LDHs) can be used as
the host for this study, synthesis of nanocomposite materials was carried out by
using Mg/Al LDH as a host of inorganic layers and naphthol blue black (NEB), fast
green (FG) and methyl orange (MO), organic dyes, as a guest It was found that the
concentrations of the organic moiety and pH are critical for the formation of the well-ordered
nanolayered hybrid materials The optimum concentration of NBB at 1 50 x
10-³ M, FG of 250 x 10⁻² M and 300 x 10² M of MO at pH 10 resulted a well-ordered
nanolayered organic-inorganic hybrid nanocomposites FTIR spectrum of
each nanocomposites resembled a mixture of each spectrum of the organic and
inorganic species, indicating the presence of both in the resulting materials Surface
morphology of Mg/AI-LDH and its nanocomposites show agglomerates of compact and non-porous structure, a typical surface morphology for LDH and Its
nanocomposites. |
